To all whom t may concern.'

Be it known that we, ARTHUR BATES and ERNEST A. CRIDLAND, subjects ofthe King of England, residing at Leicester, Leicestershire, England,have invented certain Improvements in VVork-Supports, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicatinglike parts in the several figures.

rThis invent-ion relates to improvements in or relating to machines forreforming turn shoes or for leveling the bottoms of boots or shoes.

More particularly the invention is applicable to machines for reformingturn shoes of the type described in an application for United StatesLetters Patent Serial No. 492,489 filed Apr. 27, 1909.

The object of the present invention is to provide a device for holdingthe shoe firmly on the jack or for both holding it and molding the waistof the shoe.

A feature of the invention, which is applicable to machines forreforming turn shoes or for leveling the bottoms of boots or shoes,comprises means for holding the shoe firmly on the jack or for bothholding it and molding the waist of the shoe comprising a stirrup theshoe bottom and hold it there under pressure while the shoe bottom isbeing operated upon.

As another feature of the invention the strap holding means is arrangedso that it will yield whereby the stirrup or strap is held yieldingly orresiliently in contact with the shoe bottom and preferably means is alsoprovided for varying the pressure applied by the yielding means.

These and other features of the invention, including novel details ofconstruction and important combinations of parts, will appear more fullyfrom the following description when read in connection with theaccompanying drawing and will be pointed out in the appended claims.

In the accompanying drawing,-Figure l is a front elevation of a machineembodying the present invention; and Fig. 2 is a side elevation, partlyin section, of. the machine shown in Fig. l.

or stra-p and mechanism operatively connected thereto which is adaptedto forcel the said stirrup or strap into contact with Referring to theaccompanying drawing the machine comprises an upright frame or support2at the head of which is mounted a rack bar 4. Mounted on the rack bar 4is a toe pad 6 for supporting the toe and at its other end a last pin 8for supporting the. heel end of a last upon which is carried the shoe tobe operated upon. The toe support 6 and the heel support 8 are mountedso that they can be adjusted toward and from each other by means of handwheels 10, 12.

A leather stirrup or strap 14 is adapted to embrace and bear on thewaist of the shoe as shown in Fig. 2 and is attached in any convenicntmanner, for example by hinged connections having longitudinallyextending pintles 16, 18, and transverse pivots 17, 19, to a fork oryoke 20, having arms 22, 24. The said strap is preferably attached tothe fork so that it is readily detachable. The arms 22, 24 are situatedone on either side of the rack bar 4 at points adjacent to the heelsupport as shown and the said fork or yoke 20 is provided at its lowerend or bightwith a hollow boss 26 through which passes a tubular post 28having a head 30 which is adapted to rest on the boss 26.

When the strap 14 is released from pressure against the shoe it may beraised from contact therewith by a spring 66 and may then be swungbackwardly over the heel of a shoe on the support and relatively to theyoke about the transverse pivots 17, 19, the yoke and post remaining ina posit-ion of substantially stable equilibrium over the pivot 48 aboutwhich further movementof the strap may be had if desired. By reason ofthe pivotal connection of the yoke 2O with l the post 28 the strap isadapted to be turned around by the yoke for use upon right and leftshoes without removal from the yoke which carries it. This constructionenables a non-symmetrically-shaped strap to be used which has one endthickened so as to fit the unequally inclined sides of the unsymmetricalshanks of right or left sho-es, for, as is well-known, the shanks ofshoes, particularly ladies shoes, are unequally inclined at the oppositesides, the greater lateral inclination of the shank being upon the innerside. Inside the said tubular post 28 is situated a rod 32 having ablock 34 secured thereto by means of a` knurled headed set screw 36. Aspring 38 is provided which surrounds the said rod and contacts at oneof its ends with the block 34 and at its other end with a plug 40. Theplug 40 is iiXed in the interior of the post 28 at its lower end bymeans of a clamp 42 which surrounds the lower end of the post 28 and isprovided with a screw 44 so arranged that when the screw is turned itwill act to contract the lower end of the post to hold the plug inplace, a slot 46 being provided in t-he post to permit such contraction.The rod 32 is thus yieldingly supported in the post 28.

Thelower end of the rod 32 is pivoted at 48 to a treadle 50 fulcrumed at52 to the frame 2 of the machine and it will be understood that when thetreadle is depressed the strap 14 will be pulled downwardly against theshank of the shoe through the rod 32, spring 38 and the parts justdescribed. A handle 54 is provided for raising the block 34 andconnected parts. The handle 54 has a shoulder and a reduced threadedportion which is screwed into the block, the Vshoulder preventingcontact of the threaded po-rtion with the rod 32. Slots are provided inthe post 28 for the handle 54 and the set screw 36. The pull on the workis determined by the tension of the said spring 38. In order to vary thetension of this spring the set screw 36 `is unscrewed and the block 34raised or lowered by means of the handle 54. When the requiredadjustment is obtained the screw 36 is again set up tight.

In order to hold the treadle 50 in its lowermost position andconsequently maintain the pressure on the shank of the shoe while thework is operated on, a pedal 56 is provided which is pivoted to thetreadle 50 at 58 and is acted upon by a spring 60 one end of i which isattached to the pedal 56 and the other to the treadle 50 so that whenthe treadle 50 is in its lowermost position (see Fig. 2) the pedal 56will engage, by means of a face 62, a catch 64 fixed to the frame 2 ofthe machine. It will be understood that when the pedal 56 is depressedthe face 62 will be released from the catch 64 and the treadlel 50 willthen return to its inoperative position under the action of the spring66. The face 62 and catch 64 are lheld in place by screws so that a new.face and catch can be substituted therefor if they become worn.

The screw 36 prevents rotative movement between the post 28 and the rod32 and when the treadle 50 is in its highest position it will bearagainst the top of the slot 53 and lift the post 28 bodily upward sothat the said strap is clear of the work and can he swung` awaytherefrom to enable the shoe to be lifted from 01T the jack, the saidvspring supported rod 32 swinging about its pivot48 on-the pedal 50. Theboss 26 beside being loose on the post 28 may be arranged forlongitudinal movement thereon so that the post will slide through theboss without raising the yoke when the treadle is raised by the spring66. The strap may in this case be lifted off t-he shoe by hand and hungupon the projection of the ack.
